TECHNICAL FIELD

The invention relates to a solar cell ordering system for installation planning of a photovoltaic power system, and estimating and ordering necessity members there.

BACKGROUND ART

There is a web sites in which, for people who are interested in a photovoltaic power system and who are considering for purchase of the photovoltaic power system, case examples of installation are introduced, and power generation after installation is predicted, and installable photovoltaic power systems are introduced based on a family structure, a lifestyle, a roof shape and the like. This web site enables simple pre-consideration concerning purchasing the photovoltaic power system. Moreover, this web site can provide such information at any time by internet.

The purchase of the photovoltaic power system is generally carried out as follows. First of all, a person considering of purchase makes contact with an agency dealing in the photovoltaic power system so as to have a meeting with a sales rep in the agency. At this time, the person considering of purchase has a preliminary discussion with the sales rep regarding a scale of to-be-installed photovoltaic power system (total output of electricity of the photovoltaic power system), total price for the installation, an installation data, and the like. After the meeting, the sales rep provides a planning about a method for installation and a method for connection of the photovoltaic power system based on demands of the person considering of purchase. And then, the sales rep draws up an estimate based on the planning. Subsequently, the sales rep has a meeting again with the person considering purchase using the estimate. The person considering purchase will go through a procedure of purchasing the photovoltaic power system if this estimate is agreeable.

At the same time, there is a system for advertisement, order entry, and sales of articles other than the photovoltaic power system, using internet as a sales system of the articles. In the sales system, explanations of the articles are given on a web site. In the sales system, in a case where a person who looked at the explanations of the articles on the web site and desires to purchase the articles, the person can place an order of the article on the web site.

However, there is no sales system for selling the photovoltaic power system by use of internet. This is because members of necessity for the photovoltaic power system differ depending on roofs, and works before order placement become complicated. It is therefore necessary in a case of the photovoltaic power system that a person considering of purchase and a sales rep have a meeting at the time of purchase, though information is provided by the internet.

Since the photovoltaic power system is a pricey article, the meeting is often held when a head of household has the time. Therefore, in a case where the meeting cannot be fixed, it takes a long term until next meeting. In addition, when modification is necessary, the number of the meetings will increase for it. Accordingly, it takes a long time for the person considering of purchase to finally purchase the photovoltaic power system. Furthermore, it takes a lot of troubles for works such as planning and estimation of the photovoltaic power system.
